Answer:
ok so first of all there is 14 sodas in the cooler(6+2+2+4)
and 6 of these 14 are cola 6/14 or 3/7
so 3/7 then to give your self one we multiple it by 3/7
3/7*3/7=0.18367346938
we multiple by 10
18.367346938
so the probility is 18.37%
Hope This Helps!!!

Charlie and Daniella each began a fitness programme. On day one, they both ran 500m. On each subsequent day, Charlie ran 100m more than the previous day whereas Daniella increased her distance by 2% of the distance run on the previous day.
(a) Calculate how far Charlie ran on day 20 of his fitness programme. (1) Daniella ran on day 20 of her fitness programme. On day n of the fitness programmes, Daniella runs more than Charlie for the first time.
b) Find the value of n
Answer:
a) 2400m on the 20th day for Charlie.
1) 728.41m of 20th day for Daniella.
Didn't find n, sorry.
Charlie ran 2400m on day 20 of his fitness program and Daniella ran 728m on day 20 of her fitness program.
It is given that Charlie and Daniella on day one both ran 500m on each subsequent day.
Charlie ran 100m more than the previous day.
Daniella increased her distance by 2% of the distance run on the previous day.
It is required to calculate how far Charlie and Daniella ran on day 20 and the value of n.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
Charlie ran 500m on the first day:
[tex]\rm a_1 = 500[/tex]
[tex]\rm a_2 =600[/tex] ( because charlie ran 100m more than the previous day)
It is an arithmetic progression in which the difference between two consecutive terms:
d = 600 - 500 ⇒ 100
and [tex]\rm a_n = a+d(n-1)[/tex]
[tex]\rm a_2_0 = 500+100(20-1)\\\\\rm a_2_0 = 2400m[/tex]( ∵ n = 20 )
Daniella ran 500m on the first day:
[tex]\rm b_1 = 500[/tex]
[tex]\rm b_2 = 500+ 500\times2 \%[/tex] (because Daniella increased her distance by 2% of the distance run on the previous day)
We can write [tex]\rm n^t^h[/tex] terms:
[tex]\rm b_n= 500(1+2\%)^n^-^1[/tex]
[tex]\rm b_2_0= 500(1+2\%)^2^0^-^1[/tex]
[tex]\rm b_2_0= 500(1+0.02)^1^9\\\\\rm b_2_0 = 500\times 1.02^1^9\\\\\rm b_2_0 = 500\times1.456 \Rightarrow 728.40 \approx 728 m[/tex]
[tex]\rm b_n > a_n[/tex] (given in the question)
[tex]\rm500(1+2\%)^n^-^1 > 500+100(n-1) \ \ or \\\\\rm500(1+2\%)^n^-^1 > 100n+400[/tex]
The above expression is not true for all the values of 'n' ie. 'n' can not be determined.
Thus, Charlie ran 2400m on day 20 of his fitness program and Daniella ran 728m on day 20 of her fitness programme.

Step-by-step explanation:
If you graph out the two triangles, you can see that the rotation is close to an angle of 90 - 120 degrees. And the rotation is going counterclockwise into the positives (graph quadrant IV).
(Note: a research study on coniferous trees of the American West
may sound really boring, but sometimes you might get to climb one
Scientists studying beetle infections on in Western forests discover
that in one particular region called Doug's Backyard, the number of
trees with beetle infestations seems lower than the surrounding
area. In the entire forest they're studying, the rate of severe beetle
infestations is about 0.07 (7%) of the trees, but in a sample of trees
from Doug's Backyard, they found just 0.035 (3.5%) of the trees to
be infested. Based on their statistical calculations, the likelihood that
their sample is just an accident -- that is, that the trees from Doug's
Backyard are actually infested at the same rate as the whole region -
- is 0.003, so they deem their results significant
In this story problem:
• p = 0.07
• Ô
[Select)
• Po =
[ Select)
• The p-value
[Select]
Answer:
p = 0.07
p-hat = 0.035
p0 = 0.07
p-value = 0.003
Step-by-step explanation:
p = population parameter, in this case, the rate of infestations across all trees in the forest
p-hat = test statistic, in this case, the rate of infestations found in the sample of trees, i.e. those in Doug's backyard
p0 = the null hypothesis, in this case, the rate of infestations within the forest is correctly evaluated at 0.07 or 7%
p-value = the likelihood any difference between p and p-hat is down to chance
In this case 0.003 as the p-value means there is only 0.3% probability of our statistic value of 0.035 being down to variability and chance meaning it is 99.7% likely that there is some reason behind this difference;
We would accept the alternative hypothesis which says the current parameter value, 0.07, is in fact incorrect (either too high or too low, in this case, likely too high).

Answer:
parallel
Step-by-step explanation:
maybe I guess it parallel, cause it not perpendicular
Answer:
Step-by-step explanation:
3x - 8y = 19
-8y = -3x + 19
y = (3/8)x - 19/8
32x + 12y = 19
12y = -32x + 19
y = (-32/12)x + 19/12
y = (-8/3)x + 19/12

Given that g(x)=3x - 12, what is the value of x when g(x)=-27?
Answer:
x = -5
Step-by-step explanation:
If g(x)= 3x - 12, and g(x)= -27 then -27 = 3x -12
Solve for x
-27 = 3x -12, add 12 to both sides
-27+12 = 3x, add -27+12
-15 = 3x, divide both sides by 3
-5 = x
Answer:-93
Step-by-step explanation:
g(x)=3x-12
g(x)=3(-27)-12 - Substitute
g(x)=-81-12 - Multipy
g(x)= -93 - Add

Answer:
x = 3.6
Step-by-step explanation:
If 2 chords of a circle intersect then the product of the parts of one chord is equal to the product of the parts of the other chord, that is
5x = 6 × 3 = 18 ( divide both sides by 5 )
x = 3.6
Using the intersecting chord theorem, the value of x is 3.6 cm
What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
We are given the parameters as;
the length of chords = x + 5 and 9 cm.
Using the intersecting chord theorem,
We know that If two chords of a circle intersect then the product of the parts of one chord is equal to the product of the parts of the other chord, that is;
5x = 6 × 3
5x = 18
Now divide both sides by 5
x = 3.6

The equation of the exponential function is y = 5(3)ˣ
What is an exponential function?An exponential function is a Mathematical function in the form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.
Given,
x: 0, 1, 2, 3
y: 5, 15, 45, 135
We have to find the exponential equation:
The exponential function in the form:
y = a × b ˣ
y value of x as 0 is 5.
This is the a value in the equation.
The ratio of values between x as 1 and x as 0 is 15/5 which is equal to 3. This is the value of b in the equation.
Therefore, the equation will become:
y = 5 × 3 ˣ
Hence the equation of the exponential function is y = 5(3)ˣ

the ratio of collectible pennants kyle owns to pennants that yasmine owns is 3:2 yasmine has 36 pennants . How will the ratio of kyles pennants to yasmines pennants change if they both sell half of their pennants Explain
Answer:
If they both sell half then Kyle would have 1.5:1 and Yasmine would have 18 pennants.
Step-by-step explanation:
It will change because if they both sell half, they would have to multiply by .05 or divide by 2 because that is half of something.
3/2 or 3*0.5 = 1.5
2/2 or 2*0.5 = 1
36/2 or 36*0.5 = 18
So Kyle would have 1.5:1 pennants left and Yasmine would have 18 pennants left.

patients and table #9.3.6 contains the TBV of schizophrenia patients ("SOCR data oct2009." 2013). Is
there enough evidence to show that the patients with schizophrenia have less TBV on average than a
patient that is considered normal? Test at the 10% level.

Using the t-distribution, it is found that since the test statistic is less than the critical value for the left tailed test, there is not enough evidence to show that the patients with schizophrenia have less TBV on average than a patient that is considered normal.
At the null hypothesis, we test if patients with schizophrenia do not have less TBV on average than a patient that is considered normal, that is, the subtraction is not negative, hence:
[tex]H_0: \mu_S - \mu_N \geq 0[/tex]
At the alternative hypothesis, we test if they have less, that is, if the subtraction is negative, hence:
[tex]H_1: \mu_S - \mu_N < 0[/tex]
Regarding each sample, the mean and standard deviation are found using a calculator.
[tex]\mu_N = 1463339.2, s_N = 125458.28 , n_N = 32[/tex]
[tex]\mu_S = 1445132.3, s_S = 171355.8, n_S = 30[/tex]
We have the standard deviation for each sample, hence, the t-distribution will be used.
The standard errors are given by:
[tex]Se_N = \frac{125458.28}{\sqrt{32}} = 22178.1[/tex]
[tex]Se_S = \frac{171355.8}{\sqrt{30}} = 31285.1[/tex]
The distribution of the difference has mean and standard error given by:
[tex]\overline{x} = \mu_S - \mu_N = 1445132.3 - 1463339.2 = -18206.9 [/tex]
[tex]Se = \sqrt{Se_N^2 + Se_S^2} = \sqrt{22178.1^2 + 31285.1^2} = 38348.7[/tex]
The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{Se}[/tex]
In which [tex]\mu[/tex] is the value tested at the hypothesis.
Hence:
[tex]t = \frac{\overline{x} - \mu}{Se}[/tex]
[tex]t = \frac{-18206.9 - 0}{38348.7}[/tex]
[tex]t = -0.47[/tex]
The critical value for a left-tailed test, as we are testing if the mean is less than a value, with a significance level of 0.1 and 32 + 30 - 2 = 60 df is [tex]t^{\ast} = 2[/tex]
Since the test statistic is less than the critical value for the left tailed test, there is not enough evidence to show that the patients with schizophrenia have less TBV on average than a patient that is considered normal.

A restaurant has a rectangular patio section that is 8 meters wide by 6 meters long. They want to use fencing to enclose the patio.
How much fencing will they need to go around their new patio?
meters
308
This is the answer
The restaurant will need 28 meters of fencing to enclose their new patio.
Here, we have to calculate the amount of fencing needed to enclose the rectangular patio, we need to find the perimeter of the patio.
The perimeter of a rectangle is the sum of all its sides.
Given:
Width (W) = 8 meters
Length (L) = 6 meters
The formula for the perimeter (P) of a rectangle is:
P = 2 * (Width + Length)
Plug in the values:
P = 2 * (8 meters + 6 meters)
P = 2 * 14 meters
P = 28 meters
So, the restaurant will need 28 meters of fencing to enclose their new patio.
